I had this problem with the SiS 5513, and none of this worked for me. Finally, I found someone who knew how to reinitialize the IDE channel drivers. Start regedit, and go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VXD\IOS. Delete the NOIDE value you will find there and restart. Of course, meessing with the registry carries the normal risk, but this worked for me in Win 98Ref: www.spacewalker.com/english/support/faq/w9xtip.htm
